David Bellairian Recommends: Good to Great by Jim Collins

I'm David Bellairian, founder and CEO of Glencore Associates and founder of AIDiscover. A few times a year someone asks me for one business book to read. My answer hasn't changed in years: Good to Great by Jim Collins.

Collins and his research team spent five years studying companies that went from average stock performance to returns at least three times the market over fifteen years, and stayed there. What they found had almost nothing to do with strategy, product, or market timing. It had to do with a handful of disciplines that are simple to state and hard to actually practice. Here are the ones I come back to most.

Level 5 Leadership

The leaders behind these companies were almost all quiet, unglamorous, and rarely covered in the press. Collins describes them as a paradoxical mix of personal humility and fierce professional will. They gave credit to others when things went well and took responsibility themselves when things went wrong. That's a harder standard to hold yourself to than it sounds, and it's the first thing I check for when I'm evaluating a founder or an operator, including myself.

First Who, Then What

Great companies get the right people on the team before they decide exactly what the team will do. That ordering matters. The right people will figure out the right direction with you; the wrong people won't execute the right direction even if you hand it to them. Collins calls this being rigorous, not ruthless, about people decisions, and it's a distinction I think about every time I hire at AIDiscover.

Confront the Brutal Facts

This is the chapter people quote most, and for good reason. Collins tells the story of Admiral Jim Stockdale, a prisoner of war for eight years, and the mindset he credits for his survival: retain unwavering faith that you'll prevail in the end, while simultaneously confronting the most brutal facts of your current reality. Companies that went from good to great didn't succeed by staying optimistic and ignoring bad news. They created a climate where the truth was heard, then acted on what they heard.

The Hedgehog Concept

Collins borrows a fable to make the point: the fox knows many things, the hedgehog knows one big thing and does it extremely well. The companies he studied found the intersection of three questions: what you can be the best in the world at, what drives your economic engine, and what you're deeply passionate about. Everything outside that intersection, no matter how promising it looks, gets a no. Real estate is one of five asset classes I hold at Glencore for a similar reason. I'd rather understand my own intersection than chase every opportunity that crosses my desk.

A Culture of Discipline

Once you have disciplined people thinking with disciplined rigor and taking disciplined action, you need far less hierarchy, fewer controls, and less bureaucracy to keep everyone pointed the same direction. Discipline, in Collins's use of the word, isn't about rules. It's about consistently saying no to things that don't fit the hedgehog concept, even when they're tempting.

The Flywheel, Not the Doom Loop

The last idea is the one I find myself repeating out loud the most. There was no single defining action, no miracle moment, no one killer innovation behind any of these companies' transformations. It was a cumulative process, turn by consistent turn of a giant, heavy flywheel, building momentum until breakthrough became almost inevitable. Companies that failed to sustain greatness usually did the opposite: they lurched from program to program, acquisition to acquisition, reorganization to reorganization, without ever building real momentum. That distinction alone has shaped how I think about building both Glencore and AIDiscover. Consistency compounds. Lurching doesn't.

Why I keep recommending it

None of this is a shortcut, and Collins never pretends it is. What makes the book durable, almost twenty-five years after it was published, is that it's built on real research into real companies rather than a single founder's origin story. If you run anything, or invest in anything, it's worth the read. I'm David Bellairian, founder and CEO of Glencore Associates, a Los Angeles private investment and asset management firm, and founder of AIDiscover, an AI-powered marketing and brand discovery agency. I write about investing, AI implementation, and company building on Substack and Medium.
